Which ancillary weapon benefits most from the revamped WRs?

I see Harty on the field a lot, simply because the speed/hands of him, Olave, and Kamara is nightmare fuel for DCs. There's also a pretty clear chemistry between Winston and Harty.

If everything works out, though. I think you see the biggest boom from the running backs. As Kamara and whoever else is back there with him can't be the sole focus while they double MT anymore.
